Description

Technical Field

[0001] This invention relates to the field of building energy conservation technology, specifically to a building heat recovery device. Background Technology

[0002] With the increasing demands for energy conservation and emission reduction, energy recycling in the building sector is receiving more and more attention. Building envelopes such as exterior walls and roofs generate a lot of heat under sunlight, and effectively absorbing this heat energy is of great significance for reducing building heating energy consumption.

[0003] Currently, existing building heat recovery methods mostly utilize solar collectors or solar collector tubes. For example, patent CN118168169B discloses a building heat recovery device. Through the coordination of structures such as pull ropes, racks, and pressing rods, the pressing rods can be driven to reciprocate vertically and then quickly return to their original position when the protective plate is vertically displaced. This allows the nozzles to spray water to clean the surface of the collector plate, enabling cleaning before the collector plate is covered by the protective plate. This avoids the accumulation of dust and other impurities on the surface of the collector plate, which would affect the efficiency of heat recovery and is beneficial for practical use.

[0004] However, after prolonged use, some dust will adhere to the surface of the heat collector plate. It is difficult to clean the dust by spraying water, resulting in poor performance. Furthermore, the protective plate needs to be flipped at a large angle when using it, and if the operation is incorrect, the protective plate may fall down quickly and damage the heat collector plate. Summary of the Invention

[0005] The purpose of this invention is to provide a building heat recovery device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A building heat recovery device, comprising:

[0008] A heat collection plate, with support end plates installed at both ends of the heat collection plate, a fixed bracket fixedly connected to one side of the support end plate, support legs connected to the surface of the support end plate, a drive rod rotatably mounted on the surface of the support end plate, and a guide groove formed on the surface of the drive rod.

[0009] The fixed bracket has a selection groove on its surface, and a drive chain is rotatably arranged inside the selection groove. A guide post is fixedly installed on the surface of the drive chain, and the guide post slides in conjunction with the guide groove.

[0010] A protective plate is disposed on the outside of the support end plate. The surface of the protective plate has a connecting hole. The protective plate is sleeved on the surface of the guide column through the connecting hole. A cleaning roller brush is rotatably disposed on the side of the protective plate near the heat collection plate.

[0011] Preferably, the support end plate is fixedly connected to the end of the heat collection plate by a fixing clamp, and a bearing seat and a motor seat are fixedly installed on the side of the support end plate near the heat collection plate. A servo motor is provided on the surface of the motor seat, and a synchronous pulley is fixedly installed on the output shaft of the servo motor.

[0012] Preferably, the fixing bracket is disposed on the side of the support end plate near the heat collection plate, and the inner side of the fixing bracket is provided with driving teeth.

[0013] Preferably, there are two sets of drive rods, which are respectively located at both ends of the heat collection plate. The synchronous pulleys are fixedly installed at both ends of the drive rods after they rotate through the bearing seats. A first synchronous belt is connected to the surface of the synchronous pulley on the output shaft of the servo motor at one end of the drive rod. The servo motor drives the drive rods to rotate through the first synchronous belt.

[0014] Preferably, the surfaces of the synchronous pulleys at the other ends of the two sets of drive rods are connected to a second synchronous belt, which enables the two sets of drive rods to rotate synchronously.

[0015] Preferably, the guide groove is arranged in a spiral shape.

[0016] Preferably, multiple sets of guide posts are provided. During the rotation of the drive rod, the guide posts are pushed to move through the guide groove, thereby driving the drive chain to rotate inside the selection groove.

[0017] Preferably, the protective plate is provided in multiple sets, and the multiple sets of protective plates form a protective plate with the same area as the heat collection plate. When the drive chain rotates, it drives the protective plate to move through the guide column. The two ends of the protective plate are fixedly provided with rotating shaft support frames.

[0018] Preferably, a rotating shaft is rotatably inserted into the inside of the rotating shaft support frame, and gears are fixedly installed at both ends of the rotating shaft, the gears meshing with the drive gear.

[0019] Preferably, the cleaning roller brush is fixedly sleeved on the surface of the rotating shaft, and when the protective plate moves to the upper surface of the heat collection plate, the cleaning roller brush contacts the upper surface of the heat collection plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. A servo motor drives two sets of drive rods to rotate, which in turn drive a drive chain through guide grooves. The drive chain moves multiple sets of protective plates. During the movement of the protective plates, the drive teeth drive a rotating shaft support frame through gears. The rotating shaft support frame drives a cleaning roller brush to rotate synchronously. When the protective plate moves above the heat collector plate, the cleaning roller brush rolls and scrubs the surface of the heat collector plate, thereby removing the dust adhering to the surface of the heat collector plate, cleaning the surface of the heat collector plate, and improving its performance.

[0022] 2. By installing a water spray mechanism above the heat collector plate, the water spray mechanism is activated when cleaning the heat collector plate. The water spray mechanism is used in sync with the cleaning roller brush, which further improves the cleaning effect on the heat collector plate.

[0023] 3. The drive chain moves multiple sets of continuously installed protective plates. When encountering severe weather such as hail, the drive chain moves multiple sets of protective plates to the top of the heat collector plate to protect the heat collector plate and avoid the problem of the heat collector plate being damaged by falling rapidly during the flipping process.

[0024] 4. By setting a photosensitive switch to control the servo motor, when it is nighttime or in bad weather with low light, the photosensitive switch controls the servo motor to start, driving the protective plate to move above the heat collector plate, thereby realizing the automatic protection of the heat collector plate according to the specific environment.
